' e valveshowing one arrangement of k mg r i g; 11 1s a view intransverse 5Q modification showing the parts just sell fipplicationfiled August 1915;. Serial 3:?

To all wimm it may con-com Be it known that I, RICHARD E. MEYER, acitizen of the United States of America, residing at Detroit, in thecounty of iieyne and State of lilichigen, have invented certein new anduseful improvements in R- tary-Valve Gals-Engines, of which the fol- 10me, is e specification, reference being lilfl therein to theaccompanyingdrawings.

This invention relates to valves for ex.- plosive engines and to an.arrangement thereof whereby a single port in the compression end of acylinder. is used for both. inlet and exhaust purposes the valve beingso disposed as to be balanced to large e:-:- tent and being arranged toWork noiselessly and with a minimum of liability to le iege Theinvention consists in the matt hereinafter set forth and moreparticularly pointed out in the appended claims.

In the drawings; Figure l is s view in longitudinal section of a ylinderequipped with a valve that embodies features invention, with the pistonthe end, 1. outstroke; 2 s vie taken on or about line showing the valvesthe exhaust; F 3 is it view section as Fig, :2 but with pressioiiposition; Fig. is a view so. tndiinol section ofo cylinder with that isslightly modified, the ports extended through the outer iv oi thecylinrleryFig. 5 is aview iii-section co line V-V of Fig. at showing thevalve the beginning of the exhaust; Fig. (5 is it view is section on thesame line showing th valve in closed or compression position Fig. 7 isa, view in transverse section of further modification of the valve, showi the parts before the exhaust takes place Fig. 8 is a View intransverse section of tlii the intake; Fig.9 is s view in longiturl'nssection illustrating a valve of coiioiclsi that is also an embodiment ofthe i tiozi; Fig. 10 is o View in vertical see section on or about linell-X of l v and Fig. 12 is s view 111 detail ot the j mg ring itself.

lo the drevvings,e cylinder 1 ofstsnclero .c 1 a w o=..the pistes 1 typeis equipped with a piston 2 and has it compression chamber Whose well 3that is preferably water jacketed, is provided with a spark plug opening4: in its head and e single port 5 that may be placed in connectioiieither wi h intake duct 6 through he uppervpe on of a cylinder wellproper or with passage ,7. A cylindris col valve loooy El orefeia olyhollow, ro tstobly secureo; on the compression chemiie well 3 as bymeans of a clamping that overlies an annular flange 10 at h lower end ofthe valve, the letter sbuttin the annular face formed by the shoulder onemi of the cylinder. The inner portion of the Well 8 of the valve has aport 11 lierethroegh that is in communi cation on 1 port 12 which isbrought successively into registration with the intake 6 and the exhaust7 as the valve turns. Port 11 is disposed t at it may uncover the portWhen-the port 12 is in register with the into (5 or throw the exhaustport "I into communication with the port 5 through ti) 5 eiiing 12during a sufficient ength 01 r the scavenging of the enille completed,These ports so iisposecl in relation to the intakeancl exhaust DEA I isthat the latter are nzitely openers closed tlirouglion tetive movementthe valve: is rotated by as suitable means as for by a shaft 13 gearedto the engine shaft and provided a pinion 14 which meshes with anannular gear 15 on the upper end of the sleeve the pinion and gear beingof proper to turn the valve in operative relation to the'pistoii stroke.As result of this construction the clownstroke of the cylinder occursWhile the port is in coirmiunic ion with the port 5 and the port 12 inregis. with the duct 6. On the up stroize of t "on the port 5 is seeleclg the explosion outstroke remains so (llallil of piston the scavenging;upstroke he port 11 is register tl e port 5 anal the port With theexliaust passage Y. It is to be uncleistoocl that 'ie necessary peckingrings are provided arrangements made for proper lubrii in Figs. 4-, 5siitl 6 a port 16 in the compression chamber 015 the cylinder may be[iii hronght into register successively with, a lateral eshaust port it?and intake port 18 by means of a pair oil inner ports 19 and 20 in thevalve *all and the outlet ill in the outer valve all, the latter beingconstantly in eonnnimication with both the openings 19 and 20. use of anouter cylinder sleeve in which the ports it? and 18 are tornied,thevalve being otherwise driven as in the other con.- strnetion.

To prevent pocketing of exhausted gases in the valve, the arrangementshown in Figs. 7 and 8 be used in which an intake port 23 in an outerjacket 24L, is brought into communication with a cylinder port 2-5throngh an inner opening 26 in the inner valve wall, and an. outeropening, 27 in the outer wall, While the exhaust takes place from thecylinder port through a valve opening 28 and outlet 29. This preventscontamination of the ineoming; gas by any exhausted charge which mightotherwise lod'ge'or be held in the valve Walls.

33 of the eitplosion chamber, the ring; hei? prevented by a keeper pinlllrom slnit- T he opening in the ring may correspond to the size of theport or maybe varied therefrom in order to ohange the time ofregistration. with the valve openings or to shift the lead slightly. Thering" therefore ail'ords not only eli'ective means for prevention ofleakage but also a ready Way for slightly changing the outlet of thechamber port. Furthermore as the ring" is readily renewable, the portmonth which is traversed by the valve and is therefore snbi ect to Wearmay be kept in proper shape by simply changing or refitting the ring asdesired.

A valve of this description with a cylinder of single port presentsminimum chance for leakage, is noiseless and positive in its operationand by proper proportioning (it the ports gives ample opportunity forcomplete scavenging and rapid intake.

Obviously, changes in the details of construction may be made withoutdeparting from the spirit of my invention and I do not care to limitmyself to any particular form or arrangzjen'ient oi parts.
